      PARAMETER ( PIGRK  = PIPIPI )
      PARAMETER ( ALEVEL = 8.D-03 )
*  Standard parameter for central density: it is exactly r0nucl of
*  Parevt
      PARAMETER ( RCNUCL = 1.12D+00 )
*  "Naive" r0 for sigmas
      PARAMETER ( R0SIG  = 1.3D+00 )
*  r0 for sigmas according to Kikuchi & Kawai
      PARAMETER ( R0SIGK = 1.5D+00 )
*  r0 for Coulomb barrier according to Kikuchi & Kawai
      PARAMETER ( RCOULB = 1.5D+00 )

*  Central density in nuclei
      PARAMETER ( RHONU0 = 0.75D+00 / PIGRK / RCNUCL / RCNUCL / RCNUCL )
*  For Taufor, Aefrav & Rhonuc the combinations 1 and 3 are ok. If the
*  Hannes expression for Taufor is used we must use Taufor from
*  combination 3 and Aefrav and Rhonuc from combination 1
*  Combination 3:
*3    PARAMETER ( TAUFOR = 3.0D+00 )
